Aim. To determine the concentration of blood fibrotic and inflammatory biomarkers in patients with atrial fibrillation (AF) associated with metabolic syndrome (MS) components.Material and methods. The study included 646 patients aged 35-65 years: patients with AF and MS (n=142), those with AF and without MS (n=113), those with MS and without AF (n=175) and the control group consisted of healthy subjects without cardiovascular and metabolic diseases (n=107). All participants underwent anthropometric and laboratory investigations. Profibrogenic (aldosterone, galectin-3, TGF-beta1, CTGF) and proinflammatory (CT-1, IL-6) factors were determined in serum and plasma by ELISA. Statistical analysis was performed using IBM SPSS Statistics software (version 22.0).Results. The highest concentrations of fibrotic and inflammatory biomarkers were found in patients with AF in combination with MS. In MS patients without AF, the concentration of aldosterone, galectin-3, TGF-beta1, CTGF, CT-1, and IL-6 was also higher than in healthy subjects. The levels of aldosterone, CT-1 and IL-6 in patients with AF were higher in the presence of three or more MS components, while the highest values of these parameters were found in patients with five MS components. The lowest concentrations of galectin-3, CTGF, and CT-1 in patients with AF were found in patients without MS components, and in the presence of even 1 MS component, they were significantly higher. Correlation analysis made it possible to establish a stronger relationship between aldosterone and TGF-betal with systolic blood pressure (p=0,493, p<O,O001 and p=0,530, p<O,O001), and CT-1, CTGF and IL-6 in a greater degree correlated with waist circumference (p=0,563, p<0,0001; p=0,626, p<0,0001; p=0,480, p<O,O001). The concentrations of galectin-3 and CTGF were more positively correlated with an increase in the number of MS components. In patients with AF and hypertension (HTN), but without abdominal obesity (AO), higher values of aldosterone (108,1±70,3 pg/ml and 89,3±32,2 pg/ml, p=0,003) and TGF-beta1 (3680,1±1863,3 pg/ml and 1968,1±1611,5 pg/ml, p=0,015) in serum than in AF patients without HTN and without AO. In the group of patients with AF and AO, but without HTN, higher concentrations of IL-6 (2,9±0,7 pg/ml and 1,9±0,6 pg/ml, p=0,001) and CTGF (162,9±92,2 pg/ml and 116,3±63,4 pg/ml, p=0,0001).Conclusion. It can be assumed that hypertension through the aldosterone system and TGF-beta1, as well as abdominal obesity through the cytokine system CT-1 and IL-6 activate various mechanisms and pathways for myocardial remodeling. Integral molecules galectin-3 and CTGF mediate their interactions, in particular in patients with a combination of several MS components and contribute to a higher AF risk.

The aim of this study was to determine the concentration of galectin-3, PINP and PIIINP in patients with metabolic syndrome (MS) and atrial fibrillation (AF) with an assessment of the relationship with severity of left atrium fibrosis. A total of 480 subjects were included in the case-control study: MS patients (n = 337), 176 of whom had AF, 72 patients with AF without MS and 71 healthy subjects. Galectin-3, PINP and PIIINP blood concentrations and metabolic parameters were compared with the severity of left atrium fibrosis, measured by CARTO3. Galectin-3 in AF and MS patients is higher than in MS without AF and in healthy subjects (10.3 (4.8–15.4), 5.1 (4.3–8.8), 3.2 (2.4–4.2) ng/mL, p < 0.0001). Galectin-3 serum concentration in AF patients with MS is higher than in patients without MS: 10.3 (4.8–15.4), 6.8 (5.2–8.1) ng/mL, p = 0.0001. PINP and PIIINP concentration were higher in patients with AF and MS than in MS without AF: 3499.1 (2299.2–4567.3), 2130.9 (1425.3–2861.8) pg/mL, p < 0.0001, 94.9 (64.8–123.5), 57.6 (40.5–86.9) ng/mL, p < 0.0001. Galectin-3 correlates with PINP (r = 0.496, p < 0.001) and PIIINP concentration (r = 0.451, p < 0.0001). The correlation between galectin-3, PINP and the severity of left atrium fibrosis was found (r = 0.410, p < 0.001; r = 0.623, p < 0.001). Galectin-3 higher than 12.6 ng/mL increased the risk of AF more than five-fold. High galectin-3, PINP and PIIINP concentrations were associated with heart remodeling in MS patients and increased the risk of AF.

Predictive Role

Objective: Atrial fibrillation (AF) is common in acute myocardial infarction (AMI), and galectin-3 is possibly involved in its occurrence. Galectin-3 has been shown to play a central role in fibrosis and tissue remodeling and has a role in inflammatory and proliferative responses. The aim of our study was to measure galectin-3 levels in patients with myocardial infarction and to compare its levels in patients with or without AF, in order to investigate the potential predictive role of galectin-3 in this setting. Subjects and Methods: The study included 51 consecutive AMI patients with AF; 27 AMI patients (52.9%) had permanent/persistent AF, and 24 patients (47.1%) had paroxysmal AF. Thirty-eight consecutive AMI patients without AF were used as a control group. Blood samples were obtained from venous blood on the third day after reperfusion. Results: Patients with AF had higher levels of C-reactive protein (p < 0.01) and galectin-3 (p < 0.05) than those without AF. Patients with high galectin-3 had 4.4 times greater odds of having AF. Galectin-3 levels were lower in patients without AF (p < 0.01) than in those with permanent/persistent AF. Conclusion: AMI patients with AF had higher levels of galectin-3 than those without this arrhythmia. This biomarker of inflammation and fibrosis could be a potential target for treating AMI patients at high risk.

Objective. To evaluate the epicardial fat thickness (EFT) in patients with metabolic syndrome (MS), including paroxysmal and persistent atrial fibrillation (AF). To relate EFT to the fibroid heart marker, i.e. galectin 3. Materials and methods. We examined 100 patients with MS (50 with AF), and 50 healthy persons made the control group. Serum galectin 3 was measured by ELISA method. The EFT was measured with echocardiography. Results. EFT in patients with MS was twofold higher than in healthy persons. EFT in patients with MS and AF didn't differ significantly from that in patients with MS without AF. Positive correlation between the levels of EFT and galectin 3 in serum was revealed. Serum galectin 3 and EFT were associated with atrial fibrillation in patients with MS (OR:1,27, 95% CI 1,02-1,58 and OR:1,73, 95% CI 1,37-2,19, correspondingly).Conclusion. Definition of EFT at echocardiography can be used in the assessment of risk AF in patients with MS.

Purpose. To assess the progression of atrial fibrillation in middle-aged people with hypertension in combination with comorbid extracardiac diseases.Materials and methods. In an observational cohort study, 308 patients aged 45–65 years with atrial fibrillation (paroxysmal and persistent forms) with hypertension in combination with extracardiac pathology were observed: diabetes mellitus (n = 40), thyrotoxicosis (n = 42), hypothyroidism (n = 59), abdominal obesity (n = 64) and chronic obstructive pulmonary disease (n = 47). The control group consisted of 56 patients with hypertension + AF without concomitant extracardiac disease. The level of MMP-9 was determined using the Human MMP-9 (total) Immunoassay test-system (USA); NT-proBNP —  using the NTproBNP-IFA-Best reagent kit; galectin-3 —  with ELISA —  Bender MedSystems (Austria). Echocardiography was performed using an Acuson Aspen apparatus (USA), 24-hour ECG monitoring with Schiller Medilog Holter system. All statistical calculations were carried out in the program Rstudio 0.99.879 (RStudio, USA).Results. In patients with hypertension and atrial fibrillation, the combination of diabetes mellitus (p = 0.041) and abdominal obesity (p = 0.004) is the most prognostic factor for AF progression. In groups of patients with diabetes mellitus, hypothyroidism and abdominal obesity, the most pronounced indicators of diastolic dysfunction of the left ventricle were: E/A, LVMI (men); the size of the left atrium and the end-diastolic size of the left ventricle are increased in all clinical groups. The prognostic value of biomarkers of fibrosis and remodeling of galectin-3 and MMP-9, and NT-proBNP in the progression of atrial fibrillation in patients with hypertension in combination with extracardial diseases is shown.Conclusion. There is no doubt that in case of hypertension, the decompensation of long-term hypertrophic myocardium is based on a violation of the balanced growth of its various structures and the formation of fibrosis and myocardial dystrophy, which was confirmed in the present study. The detected elevated levels of MMP-9, galectin-3 and NT-proBNP, as well as ultrasonic signs of myocardial remodeling, confirmed that they statistically significantly affect the progression of atrial fibrillation. In this regard, a personalized approach to a patient with atrial fibrillation in combination with comorbid pathology is required, especially in middle-aged people at the stage of comorbidity formation, under the conditions of received diagnostic information on the electrical function of the heart and assessment of the functional capabilities of CVS during its transition to various levels of functioning.

Introduction: We aimed to compare serum levels of S100B between patients with metabolic syndrome and healthy subjects and to investigate the association of S100B with components of the metabolic syndrome.Materials and Methods: In this study, 44 patients with metabolic syndrome and 44 healthy subjects participated. The participants’ body mass index, waist circumference, systolic and diastolic blood pressure were measured. Serum levels of low and high density lipoprotein cholesterol, total cholesterol, triglyceride, fasting blood glucose, insulin, S100B protein were determined by enzymatic and ELISA methods.Results: The participants with metabolic syndrome had significantly higher levels of S100B than those in the control group (p < 0.0001). Serum levels of S100B protein were positively correlated with abdominal obesity (rho = 0.26; p = 0.01) and serum levels of triglyceride (rho = 0.26; p = 0.01). Moreover, serum levels of S100B were higher in subjects with abdominal obesity (p = 0.02), with higher serum triglyceride levels (p = 0.03) and with hypertension (p = 0.01).Conclusion: The findings indicate that there may be a link between S100B protein with abdominal obesity and serum levels of triglycerides. This warrants further research to elucidate whether increased S100B levels in patients with metabolic syndrome are involved in the pathogenesis of cardiovascular disorders.

Underlying Mechanisms

During the last few years, a significant number of studies have attempted to clarify the underlying mechanisms that lead to the presentation of atrial fibrillation (AF). Inflammation is a key component of the pathophysiological processes that lead to the development of AF; the amplification of inflammatory pathways triggers AF, and, in tandem, AF increases the inflammatory state. Indeed, the plasma levels of several inflammatory biomarkers are elevated in patients with AF. In addition, the levels of specific inflammatory biomarkers may provide information regarding to the AF duration. Several small studies have assessed the role of anti-inflammatory treatment in atrial fibrillation but the results have been contradictory. Large-scale studies are needed to evaluate the role of inflammation in AF and whether anti-inflammatory medications should be routinely administered to patients with AF.

Abstract“Glycans”, which are generally referred as oligosaccharides and polysaccharides, are structures that are present on all cellular surfaces with proteins and lipids being attached to their basic chain structures. Many studies in the field of glycobiology have identified the various and complicated biological roles of these glycans which make them perfect molecules to use in labelling and selecting body cells specifically. This study aims at analyzing the modifications in saccharide units of glycans on a cell membrane surfaces of the pancreatic tissue of rats to which normal and metabolic syndrome (MetS) are established. To this end, a MetS model was created through a high fructose diet in Spraque Dawley breed of rats and the pancreatic tissue sections of the group with MetS and control group animals were evaluated comparatively. The targeted saccharide units were examined with Fluorescent Microscope by using two different Fluorescein (FITC) labelled lectins, namely Maackia amurensis-1 lectin [FITC-(MAL-I)] and the Wheat Germ Agglutinin (FITC-WGA). It was observed that FITC-MAL-1-labelled Galβ4GlcNAc units did not change much due to high- fructose diet. On the other hand, more GlcNAc, Neu5Ac and β-GlcNAc units which are labelled with FITC-WGA lectin increase in numbers in pancreatic sections of high fructose diet, compared to control group. Thus, a rapid and specific labelling method, which can identify surface saccharide sequences specifically, was developed. The method can be used in early diagnosis and/or treatment for metabolic diseases.

The metabolic disorders are major health issues of today’s scenario and incidences of metabolic diseases increases day by day due to the disturbed pattern of life style. Ayurveda texts have described term “Santarpanjanya Vikaras” which resembles diseases of defective tissue metabolism. Ayurveda mentioned that improper dietary habits and sedentary life style affects state of Agni which resulted Ama production and finally leading to the metabolic syndrome. The vitiation of Dosha, diminish state of Dhatu and blockage of channels, etc. also can initiate pathogenesis of metabolic disorders. The Kayachikitsa branch of Ayurveda recommended use of internal medicine for the management of various metabolic disorders. Considering increased health burden of society due to the metabolic syndrome present article explore role of ayurveda internal medicine for the management of metabolic syndrome. Keywords: Ayurveda, metabolic syndrome, Santarpanjanya, Madhumeha and Sthoulya.
